Description
This page contains the results for the final fates simulation, using
the fitted model object.
Simulation steps
For each combination of origin and rear type, the following steps
were run:
- Extract the median covariate values experienced by all fish in the
dataset (for spill window, winter spill days, and temperature). For
spill window and temperature, these median values are separately
estimated for fish moving upstream (previous state a downstream mainstem
state) vs. moving downstream (previous state an upstream mainstem state
or a tributary), as well as for fish moving during the winter/spring and
summer/fall. This results in four different median temperatures
(winter/spring, upstream; winter/spring, downstream; summer/fall,
upstream; summer/fall, downstream) These values are then used in the
simulation.
- Randomly select one iteration from the model (one set of draws for
all parameters). When given the choice, parameters corrected for
detection efficiency were chosen (no parameters were used that were only
estimated for years where detection efficiency was not estimated).
- Simulate 1,000 fish that start at Bonneville Dam and move through
the basin, with movements governed by the median covariate values and
the values of the parameters from that iteration of the model.
- Repeat steps 2 and 3 1,000 times, for a total of 1,000,000 simulated
fish.
For each tributary, the final fates are plotted. If a tributary has
both a hatchery and natural origin population, the final fates are
compared.
Notes
- A consistent issue across many populations is an overestimation of
straying rates, particularly into the Deschutes River. See the
“Outstanding issues” tab for more information on this issue, which I am
still trying to resolve.
- The Grande Ronde, Salmon, and Clearwater Rivers all do not have
arrays set up to estimate detection efficiency, which is why their
mainstem final fates are much higher.
Final fates - fit to data
Below is a plot comparing the simulated final fates to those observed
in the data. For this plot, the final fates from the data only includes
the years where detection efficiency was estimable (meaning that there
was both a river mouth site and upstream sites available). This includes
detections at both mouth and upstream states, whereas the model only
models detections at the mouth site (but uses the upstream sites to
estimate detection efficiency at that site). While not a perfect
comparison, this gives a feel for how well the simulated final fates are
fitting the data.
Final fates, from the model vs. the data.
Some observations:
- The model estimated final fate in the home state is frequently (but
not always) higher than that from the data, and mainstem final fates are
frequently lower than that from the data. This may be due to the
detection efficiency correction.
- The Deschutes River (points) is fairly consistently overestimated
for Middle Columbia populations, but the only populations where this
overestimation is severe is Fifteenmile Creek and Umatilla River
(hatchery)
